Meta’s 2020 research project, Project Mercury,
measured the effect of ‘deactivating’ Facebook & Instagram
According to Meta docs obtained via discovery…

Sex trafficking on Meta platforms was both difficult to report and widely tolerated.

There’s a line in the Times piece about Dominic Cummings claiming that the Cabinet Office secure systems had been breached by China circa 2020:
“He said he was warned at the time that disclosing some specific details of the breach would be a criminal offence.“
And I presume this is Official Secrets Act, but no article mentions this?

I have owned my 2016 EV since 2020. (I like buying my cars four and a half years old because four years is the length of a typical lease and when supply goes up, price goes down). I like the fact that (because it's an EV), beyond tire rotations, it's only been in the shop once. That one time, was due to the fact that the start button got stuck in and wouldn't come out again.

Spectral gap for the signed interchange process with arbitrary sets
In 2020, F.Cesi introduced a random walk on the hyperoctahedral group $B_n$ and analysed its spectral gap when the allowed generators are transpositions and diagonal elements corresponding to singletons. In this paper we extend the allowed generators to transpositions and any diagonal elements, and characterise completely the set of representations from which the spectral gap arises. This settles a conjecture posed in Cesi's paper.
